may concern:

Be it knownthat we, EDWARD A. GARVEY and CHRISTOPHER of America, residing at in the State .of Missouri, have invented certain new and useful Improvements in Fountain Marking and Stencil Brushes, of which'th'e following is a full,

clear, and exact description, reference being -10.

had. to the accompanying drawing, forming part of this specification.

' a fountain brush for use in markin packages of merchandise .eitherwith'or without the use pf a stencil and the present invention has for its object to prov de the fountain of a brush of this'character with simple and etficient valve conlhng means separable from the shell of the c fountaln to permit thorough cleansing of the the possiblht the bristles is a similar view to parts so constructed as to' eflectually obviate of escape of ink from the fountain when the brush is not in use and lying in a horizontal position.

igure I is a longitudinal section. taken throu l1 our brush with the outlet valve and air vsive shown in open positions. Fig. II Fig. I with the outlet valve in a seated position and the air valve :eceded from the valve red, the central portion of the reservoir being broken out and of the brush being omitted.

Fi III is a cross section taken on line IIl III, Fig. II. Fi IV is a cross section taken on line IV-IV, 1g. II.

eferring to the accompanying drawings: 1 designates the cylindrical shell of the fountain of our brush which consists of a'single tube that is threaded internally at its ends.

2 is a socket piece that is screw-threaded internally and provided with an externally removably attached to the inner end of the fountain shell 1 and which is provided with a diaphragm 4 that contains a central orifice 5. The diaphragm bears abridge or spider 6 located at the outer side of the diaphragm and from which projects a tubular guide stem 7, the bore through said guide stem being in line with the central orifice 5 in the dia )hragm of the externally screw-threaded soclrct piece 2.

. 8 is a flanged pocket piece that is removably held in the socket piece 2 due to screw threaded-engagement between these menibers and in which the The pocket piece-is 1O located'eentrally bristles 9 are seated. provided with a iii of it andthrough W ich A. GARVEY, both citizens 'b 1 0f the United States g the city of St. Louis,

ple trolling I markingfluid may pass from the space A within the socket piece 2 to the bristles rush.

11 designates a valve rod that is loosely seated in the guide stem 7 carried by the bridge 6 of the socket piece '2, and 12 is a valve fixed to said valve rod and located in 'he space A within the socket ieee. valve just mentioned is adapte to seat in the central orifice 5 of the socket piece of the through the nipple 10 to the brush bristles and said valve is also adapted to be unseated from its position in said central orifice to the position shown in Fig. I, whereb the marklng'fiuid may flow into the space X from to the brush bristles. l

13 is aretracting spring that is connected to the guide stem 7 and surrounds the valve rod 11, the spring said guide stern and acollar or button 14 that is fixed to the valve rod in order that the spring may act upon said valve rod for the purpose of moving the valve .12 to its seat when the valve rod is free of restraint.

15'is a guide spider that is carried by the valve rod and the arms of which are adapted to move freely within the main chamber of the shell 1 'of the brush fountain for the purpose of directing the movement of said valve rod longitudinally of said fountain shell.

16 designates a stopper or plug that has an externally screw-threaded neck which is detachably fitted to the end, of the fountain shell 1 opposite that to which the socket piece 2 is attached and which is adapted to be disconnected from the fountain shell to permit filling of the fountain in the brush. In the center of the stopper 16 is a screw threaded bore 17. i

18 is a valve controlling screw that is seated in the screw threaded bore of the stopper'and is adapted to be moved inwardl and outwardly in said. screw threaded bore for the purpose of moving the valve rod 11 to unseat the and valve rod to be carried outwardly under the influence of the retracting spring 13.

At the inner end of the valve controlling screw is a pocket 19 which is preferably of concave shape and in which the outer end of the valve rod 11 seats whenv the valve conscrew is moved inwardly in the stopper containing it, for the purpose of The beingconfined between valve 12 or permit said valveand therethat the 'end of the valve r0 In the valve controlling screw is an angular air duct 20v that extends longitudinally trated in Fig.

ling I the ,position seen in of the valve controlling screw from its outer end and then transversely of the valve controlling screw to the exterior thereof at a oint intermediate of the ends of the valve controlling screw, this angular air duct hitVw mg the utility of permitting the entrance of air into the main chamber of the brush founta n when the valve controlling screw is moved inwardly in the act of unseating the valve 12 in order that the requisite amount of air may be supplied in said main chamber to occasion the flow of marking fluid therefrom to the bristles of thebrush. The air duct terminates at its inner end at a. point that 'permits of communication of 'the ,air duct with'the of the .brush when the valve. controlling screw is moved inwardly to the extent illus- I and which provides for the air duct being closedat its innerend when the valve controlling screw is retracted into I Fig. II at which time the inner end of the air duct is confined within a central, sleeve 16 forming apart of the stopper 16 controlling screw extends.

When the valve controlling screw is retracted in the position last-referred to, the marking fluid cannot, if the valve controlscrew is snugly fitted in the stopper 16, flow from the bristles thereof when the brush is not in use, due to the inner end of the air duct in the valve controlling screw being out of communication with the main chamber and thefountain of the brush.

To afford additional security against the' entrance of air into the fountain chamber and thereby occasion flow .of marking fluid therefrointo the brush bristles when the brush is not in use, we provide upon the valve controlling screw between the inner end of the air duct 20 and the inner end of said screw, an annularrib or collar 21 that opposes the central sleeve 16 of the stopper 16 and is adapted to ser e as a packing or closure by contact with said central sleeve whereby any air that might find its way between the valve controlling screw and the bore in the stopper 16 1s revented from gaining access to the main 0 amber of the brush fountain.

The annular rib 21 main chamber of the fountain and through which the valve' and provided with preferably has seated upon it a leather or other a aptedto contact with the'inner en the central the parts appertaining thereto are withdrawn from the fountain shell. It will also be seen that when the stoptper is removed from the fountain shell, sai fountain shell contains no interior obstruction from end to end thereof. It will also be noted the pocket piece .in. which the the brush are seated tached from the socket piece 2 rendering said socket piece as well as the parts associated with it, readily accessible to be thoroughly cleansed.
